This is a ListBox issue, which is part of the runtime. It's been fixed as part of the Windows Phone 8 release.

This issue also appears in the standard ListBox control whenever list items have different heights. You don't necessarily need to have wrapping text, just a height difference between the items that appear in the list (such as group headers that are significantly shorter than the list items). As far as I can tell, the issue only appears after selecting an item, but clearing the selected item or setting the SelectedIndex to -1 doesn't seem to fix it.
